View existing layouts

[Susan Spencer]

If previous Layouts exist for a pattern design, user can select existing layout or create new layout. The layout is saved with pattern name, measurement name, date and time in layout filename.

I don't like this idea. First, for this need make special format for saving a layout.
Second, much quicker way just regenerate a layout again. Algorithm generate each time same result for same settings.
Third, if you don't like generation speed better spend time improving this part.
Forth, saving a layout bad idea because you can't guarantee that pattern was not changed. And in most cases it will be.

Such plain data about a layout you will need only if you have another program that use it.

I see only one case where it will be useful. If you don't want spend time for generation. But i think it is too early make such optimizations. It will be useless spend of time.

Fair enough. Agreed. But eventually will the user need to review & purge old layouts? We can hold off on this, not important for now.
